Description

Technical Field

[0001] The present invention relates to the technical field of high-voltage wire harness detection, and in particular to a universal high-voltage wire harness end sheath detection tool. Background Art

[0002] High-voltage wiring harness is one of the indispensable components inside new energy vehicles. It is mainly used to stably transmit electrical energy, shield external signal interference, and ensure the safe and stable driving of new energy vehicles.

[0003] Before being installed on a vehicle, high-voltage wire harnesses usually need to be covered with a sheath at their ends to prevent short circuits, abrasion, or damage to the high-voltage wire harnesses from the external environment, thereby ensuring the stable operation of the vehicle's electrical system.

[0004] Conventional technology primarily relies on manual or semi-automated installation of sheaths. However, due to the specific materials, dimensions, and installation locations of the sheaths, problems such as improper installation, damage, or omissions can easily occur. If these issues are not discovered promptly, they can lead to serious safety hazards such as insulation failure, short circuits, and even fires in the high-voltage wiring harness during vehicle operation.

[0005] At present, the industry mainly uses detection devices for automated detection of sheath installation quality. However, there are many types of high-voltage wire harness sheaths, and detection devices often require high-precision sensors, complex image processing systems or customized mechanical structures, resulting in high overall costs. It is impossible to ensure that each high-voltage wire harness sheath can be equipped with a detection device. Summary of the Invention

[0006] In view of this, the present invention provides a universal high-voltage wire harness end sheath detection tool, which can be used to detect high-voltage wire harness sheaths of various specifications to reduce costs.

[0007] To achieve the above purpose, the technical solution of the present invention is as follows:

[0008] A universal high-voltage wire harness end sheath detection tool comprises a base, a detection mechanism and a sheath mounting assembly arranged opposite each other are provided on the top of the base, and the characteristic is that a mounting seat is slidably mounted on the sheath mounting assembly, the sliding direction of the mounting seat is perpendicular to the opposite direction of the detection mechanism and the sheath mounting assembly, a plurality of grooves are distributed on the top of the mounting seat along its sliding direction, each of the grooves is used to position and install sheaths of different specifications, and the mounting seat can be slid so that any of the grooves is opposite to the detection mechanism.

[0009] By adopting the above structure, through the grooves of various sizes formed on the top of the mounting seat, when it is necessary to detect the sheath of the corresponding size, it is only necessary to slide the mounting seat and align the groove of the corresponding size with the detection mechanism. This is very convenient and quick. In addition, the grooves of various sizes also increase the use scenarios of the detection mechanism and reduce the production input cost.

[0010] Preferably, the sheath mounting assembly further comprises a base, the top of the base being provided with two parallel slide rails, a slider being slidably mounted on the slide rails, and the mounting seat being fixedly mounted on the top of the slider. With the above structure, the mounting seat can slide stably and directional.

[0011] Preferably, the bottom of the mounting base has an extension extending toward the detection mechanism, with first positioning holes distributed on the extension, each of the first positioning holes corresponding to each groove. The base is provided with a lifting cylinder, which is arranged opposite the detection mechanism. The mounting base is slid so that the end of the cylinder rod of the lifting cylinder can be inserted into each of the first positioning holes. With this structure, by inserting the end of the cylinder rod of the lifting cylinder into each of the first positioning holes, each groove can be precisely stopped at a position opposite the detection mechanism, thereby ensuring detection accuracy.

[0012] Preferably, the mounting base has a flip-up cover plate on top, which is used to cover the top of the groove. The cover plate is provided with a vertically downward-extending pressure block corresponding to each groove position. When the cover plate is installed on the top of the mounting base, the bottom of the pressure block can abut against the top of the sheath. This structure can ensure that the sheath is locked in place, further ensuring detection accuracy.

[0013] As a preference, the sizes of the grooves are the same. With the above structure, multiple sheaths of the same model can be placed at the same time, thereby speeding up the detection of sheaths of the same model.

[0014] Preferably, the base includes an upper base and a lower base, wherein the lower base is fixedly arranged on the top of the base, and the upper base is detachably arranged on the top of the lower base. The above structure can facilitate the replacement of the upper base with different grooves.

[0015] Preferably, a resistance positioning device is provided between the mounting seat and the base, the resistance positioning device comprising a roller, a resistance positioning block, and a lifting seat. The lifting seat is slidably mounted on the upper base via an elastic component. The roller is rotatably mounted on the lifting seat. The resistance positioning block is fixedly mounted on the bottom of the mounting seat. The bottom of the resistance positioning block is provided with a plurality of upwardly concave arcuate grooves, each of which corresponds to each of the first positioning holes. With the above structure, when the mounting seat slides to the arcuate groove, the elastic component causes the roller to lift upward, thereby facilitating rapid positioning between the lifting cylinder and the first positioning hole.

[0016] Preferably, a second positioning hole is provided on the top of the lower base, and a positioning pin extends downward from the bottom of the upper base, the positioning pin being inserted into the second positioning hole.

[0017] Preferably, a locking member is provided on the upper base, and the locking member is used to connect the upper base and the lower base into one body. The above structure can ensure that the upper and lower bases are firmly connected, and avoid the upper base shaking and causing deviation in the detection position.

[0018] Preferably, the detection mechanism is a photographic detection device or a depth sensing device. With the above structure, the installation quality of each sheath can be detected efficiently and accurately.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The universal high-voltage wire harness end sheath detection tool provided by the present invention has grooves of various sizes formed on the top of the mounting seat. When it is necessary to detect the sheath of the corresponding size, it is only necessary to slide the mounting seat and align the groove of the corresponding size with the detection mechanism. This is very convenient and quick. In addition, the grooves of various sizes also increase the use scenarios of the detection mechanism and reduce the production input cost.

[0021] 2. Through the design of the lifting cylinder and each first positioning hole, each groove can be accurately stopped at the position opposite to the detection mechanism, ensuring the detection accuracy of the detection mechanism.

[0022] 3. The sizes of each groove can also be set to the same size, which greatly speeds up the detection efficiency of sheaths of the same size.

[0023] 4. The base adopts a detachable structure, and the upper and lower bases are fixedly connected only by locking parts. Compared with disassembling and replacing the mounting base, disassembling the upper base is more convenient and quick. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The present invention will be further described below with reference to the embodiments and accompanying drawings.

[0035] like Figure 1 and Figure 2 As shown, a universal high-voltage wire harness end sheath detection tool includes a base 1, on the top of the base 1 are arranged a detection mechanism 2 and a sheath mounting assembly A, a mounting seat 3 is slidably mounted on the sheath mounting assembly A, the sliding direction of the mounting seat 3 is perpendicular to the facing direction of the detection mechanism 2 and the sheath mounting assembly A, a plurality of grooves 3a are distributed on the top of the mounting seat 3 along its sliding direction, each groove 3a is used to position and install sheaths 10 of different specifications, and the sliding mounting seat 3 can make any groove 3a face the detection mechanism 2.

[0036] With such a design, through the grooves 3a of various sizes formed on the top of the mounting seat 3, when it is necessary to detect the sheath 10 of the corresponding size, it is only necessary to slide the mounting seat 3 and align the groove 3a of the corresponding size with the detection mechanism 2. This is very convenient and quick. In addition, the grooves 3a of various sizes also increase the use scenarios of the detection mechanism 2 and reduce the production input cost.

[0037] In this embodiment, the grooves 3 a can also be set to the same size. In this case, multiple sheaths 10 of the same model can be placed on the mounting base 3, which greatly speeds up the detection efficiency of sheaths 10 of the same size.

[0038] In this embodiment, the detection mechanism 2 can be a photographic detection device or a depth sensing device. Since both belong to relatively mature existing technologies, their specific structures and principles will not be repeated in detail in this embodiment. Through the detection mechanism 2, the detection accuracy of the sheath 10 can be guaranteed, and the sheath 10 can be ensured to be installed in place.

[0039] like Figure 1 and Figure 4 As shown, the sheath mounting assembly A also includes a base 4, which is fixedly mounted on the top of the base 1. Two parallel slide rails 5 are fixedly mounted on the top of the base 4, and sliders 6 are slidably mounted on the slide rails 5. The mounting seat 3 is fixedly mounted on the top of the sliders 6. This design achieves stable directional sliding of the mounting seat 3.

[0040] For example Figure 4 and Figure 7 As shown, limit blocks 12 are fixedly installed at both ends of the top of the base 4 corresponding to the sliding direction of the mounting seat 3, and two limit blocks 13 are fixedly installed at the bottom of the mounting seat 3. The two limit blocks 13 are arranged between the two limit blocks 12. Through the mutual cooperation between the limit blocks 12 and the limit blocks 13, the sliding stroke of the mounting seat 3 can be further limited to prevent the slider 6 from hitting the base 4 and affecting the service life of the slider 6.

[0041] Further, such as Figures 3 to 5 As shown, the base 4 includes an upper base 4a and a lower base 4b, wherein the lower base 4b is fixedly mounted on the top of the base 1, the upper base 4a is detachably mounted on the top of the lower base 4b, and the mounting seat 3 is slidably mounted on the top of the upper base 4a. In this embodiment, two rows of parallel grooves 3a are formed on the top of the mounting seat 3. By horizontally rotating the upper base 4a 180° and reinstalling it on the lower base 4b, the groove 3a originally away from the side of the detection mechanism 2 can be made to face the detection mechanism 2, further increasing the usage scenarios of the detection mechanism 2.

[0042] In order to facilitate the operator to disassemble the upper base 4a, in this embodiment, handles 8 are fixedly installed at both ends of the upper base 4a corresponding to the sliding direction of the mounting seat 3. For details, see Figure 1 and Figure 4 .

[0043] like Figure 3 and Figure 5As shown, a second positioning hole 4b1 is formed on the lower base 4b, and a positioning pin 4a1 extends downward from the bottom of the upper base 4a. The positioning pin 4a1 is used to pass through the second positioning hole 4b1. Such a design can facilitate the rapid positioning and installation of the upper base 4a on the lower base 4b, and at the same time avoid deviation in the installation of the upper base 4a, which may affect the detection results of the detection mechanism 2.

[0044] like Figure 4 As shown, two sets of locking components 9 are provided on the upper base 4a. The locking components 9 are used to securely connect the upper base 4a and the lower base 4b together, preventing the upper base 4a from shaking and affecting the detection accuracy of the detection mechanism 2. In addition, the locking components 9 make it easier to disassemble the upper base 4a. In this embodiment, the locking components 9 are quick-release fasteners, but they can also be fixed using locks, bolts, or other methods.

[0045] like Figure 1 and Figure 6 As shown, the bottom of the mounting seat 3 has an extension portion 3b extending toward the direction of the detection mechanism 2, and four first positioning holes 3c are distributed on the extension portion 3b. Each first positioning hole 3c is arranged in a one-to-one correspondence with each groove 3a. A lifting cylinder 7 is also fixedly installed on the base 1. The installation position of the lifting cylinder 7 is arranged opposite to the detection mechanism 2. The sliding mounting seat 3 can make the cylinder rod end of the lifting cylinder 7 pass through each first positioning hole 3c, so that each groove 3a is facing the detection mechanism 2, thereby ensuring the detection accuracy of the detection mechanism 2 on the sheath 10 in each groove 3a.

[0046] like Figure 4 、 Figure 7 、 Figure 8 and Figure 9 As shown, a resistance positioning device 11 is also provided between the mounting base 3 and the base 4. The resistance positioning device 11 includes a roller 11a, a resistance positioning block 11b, and a lifting base 11c. The lifting base 11c is slidably mounted on the upper base 4a via an elastic component 11d. The roller 11a is rotatably mounted on the lifting base 11c. The resistance positioning block 11b is fixed to the bottom of the mounting base 3. The bottom of the resistance positioning block 11b is formed with four upwardly concave arcuate grooves 11e. The four arcuate grooves 11e are arranged one-to-one with the four first positioning holes 3c. During the sliding of the mounting base 3, the upward thrust exerted by the elastic component 11d on the lifting base 11c can push the roller 11a upward into each arcuate groove 11e. When the roller 11a moves into the arcuate groove 11e, the first positioning hole 3c and the lifting cylinder 7 can be quickly positioned. In this embodiment, the elastic component 11d is a gas spring or a compression spring.

[0047] For example Figure 10As shown, a rotatable electric turntable 11f is mounted on the upper base 4a, and a lifting seat 11c is slidably mounted on the electric turntable 11f via a guide rod a. When the mounting seat 3 slides to the point where the groove 3a is aligned with the detection mechanism 2 (detection position), the electric turntable 11f drives the lifting seat 11c to rotate horizontally 90°, allowing the roller 11 to rotate 90° within the arcuate groove 11e. At this point, a locking structure is formed between the roller 11 and the arcuate groove 11e, which can create a large sliding resistance for the mounting seat 3. Based on this, the limiting structure formed between the first positioning hole 3c and the lifting cylinder 7 mentioned above can be omitted, thereby optimizing the compactness of the tooling.

[0048] like Figure 6 As shown, a cover plate 3d is installed on the top of the mounting base 3. The cover plate 3d is used to cover the top of the groove 3a. A pressure block 3e is formed vertically downward at the position corresponding to each groove 3a on the cover plate 3d. After the cover plate 3d is installed on the top of the mounting base 3, the bottom of the pressure block 3e can abut the top of the sheath 10. This design, through the cover plate 3d and the pressure block 3e, can ensure that the sheath 10 is stably mounted within the groove 3a, further ensuring the detection accuracy of the detection mechanism 2. In this embodiment, the cover plate 3d and the pressure block 3e are only suitable for smaller sheaths 10, that is, the sheath 10 can be completely mounted within the groove 3a. They are not suitable for sheaths 10 that are larger than the depth of the groove 3a.

[0049] Finally, it should be noted that the above description is only a preferred embodiment of the present invention. Under the guidance of the present invention, ordinary technicians in this field can make various similar expressions without violating the purpose and claims of the present invention. Such changes fall within the scope of protection of the present invention.
